Final answer:
A solution with greater extracellular osmotic force than the intracellular environment is termed a hypertonic solution, leading to water exiting the cell. Therefore, the most appropriate correct option is C.
Step-by-step explanation:
Solutions in which the extracellular osmotic force is greater than the intracellular environment are known as hypertonic solutions. In a hypertonic solution, the concentration of solutes outside the cell is higher than inside, leading to a net flow of water out of the cell as it attempts to balance the solute concentration on both sides of the cell membrane. This can result in the cell shrinking and shriveling. Conversely, a hypotonic solution means that the extracellular environment has a lower osmolarity than inside the cell, causing water to flow into the cell.
An isotonic solution is one where the osmotic pressure outside and inside the cell is equal, resulting in no net water movement across the cell membrane.
